Since it first aired in 1996, “Arthur” hasn’t mentioned Mr. Ratburn’s sexuality until now, though the word “gay” wasn’t used in the episode, according to TVLine.

The outlet also reported that Mr. Ratburn isn’t the first openly gay character in the “Arthur” universe.

In a 2005 “Postcards from Buster” episode, the cartoon rabbit and friend of Arthur’s met children in Vermont whose mothers were lesbians, though the word “lesbian” was never said in that episode either, TVLine reported.

After the newest episode aired on Monday, people on social media were delighted by the news of Mr. Ratburn’s wedding to a man.
